    I ordered a RAW HM1000x in .25 cal. I am pondering the barrel. This will be a hunting gun. I like shooting Kings and Polymags. If you have a polygon barrel do you shoot Polymag pellets/velocity? Does the LW rifled barrel shoot Polymag pellets accurately/velocity?
     
    Is there a RAW picture thread?

    Thanks.

    Just so you know LW makes a standard barrel and a polygon profile barrel.  In 17 and 22 cal the polygon barrel has 6 grooves as opposed to 12 grooves in a standard barrel.  In 25 cal both have 10 grooves.  My opinion is that when you are shooting pellets the twist rate is not as big a deal as with bullets because the pellet skirt will confirm to the barrel grooves anyway.  I think PCP technology has surpassed pellet technology to the point where almost any high end PCP will pretty much perform equally.  If you look at any of the videos about this or that PCP when the range gets out to 100 yards the weather/wind conditions are the biggest factors. The reality is that as far as consistent performance, 1 ” groups at 100 yards is about the best you will get.  Sure there will be times when the stars align and you get perfect shooting conditions and get a smaller group.  But under normal shooting conditions, 1/2″ at 50 yards and 1″ at 100 yards are what you will get.  You can spend $700-$2200 and it’s not going to change.

    Martin at RAW sets up the standard LW for Kings. The optional LW polygon is set up to shoot the the Heavies at a faster speed than the standard can deliver accurately, with more power. I don’t know what a polymag weighs, but if it is light, I would keep the speed down and use the standard barrel.
    Give RAW a call, Martin will let you know himself what you are asking for. They will set it up the way you like. You may also request a heavier trigger pull for hunting.

    are you going to get the single shot with thimble indexing for max accuracy.. my gun has thimble for indexing and its amazing how much better a gun is when using a thimble.

    aa, I have no idea what thimble indexing is.

    RAW HM means Hunting Master, TM means Target Master.  They are very close but tuned differently.

    The barrels with a thimble can only be fitted on the TM and BM models which, I believe, share the same design.. The TM/BM receiver and HM receivers are of different design. The receivers on the HM1000 and HM1000x are also different.
    I have a HM1000 that shoots the 25.4 JSB at around 860 fps. The HM1000 with its smaller plenum is pretty well maxed out at this point. It has the standard Walther barrel and will shoot 1/2″ at 50yds. I have the gun zeroed at this distance and have not grouped it at longer distances. I have connected with ground squirrels out to about 90yds in the field. 
    The .25 is a lot of fun.

    But what the hell is a thimble and how does it affect accuracy?

    Call Martin…. RAW offers a lot of options for different applications. They cost too much to not get the correct one for your application. I own a RAW LRT .25 LW cut barrel and love it. I’ve had it about one year and there are more options now. Don’t get hung up with indexing and barrel types . There are advantages and disadvantages to all configurations. Tell Martin what you want. He will know what best meets your wants. You are ordering a custom airgun. Good luck …..

    The only thing the thimble does is allow you to rotate/index the barrel. The transfer port in the RAW is drilled through the barrel, so if you try to rotate it it will not align with the plumbing of the receiver. The drilled thimble in the TM/BM does not rotate, but it is coupled to the barrel that can. Rotating the barrel allows you to adjust for the bore not being aligned to the barrel exterior or mounting recess. Barrels are normally rotated to the point where they give the highest POI. This, I guess, gives the best position to tame barrel harmonics.
    Rotating barrels has been popular with firearm BR shooters for many years. There is no magic here,

    “blackdiesel”But what the hell is a thimble and how does it affect accuracy? 

    
Instead of the one piece barrel which includes the transfer port, is fixed. With a two piece (thimble screwed to the end). The barrel can be slightly bent. So the barrel can be indexed (turned) to change poi. For example if you turn a barrel 360 and shoot it every 10 degrees it would shoot a circular pattern. If that makes sense. Like stated above our HM/X receivers have a one piece barrel that has a transfer hole at the bottom.

    Thinking about it, the non rifled thimble might aid the pellet to pass over the transfer port without damage .

    anyone who has ever used a thimble will tell you that they do work. for instance wth barracuda 10.6 g  at 5 oclock I was able to half group size with that one pellet it was amazing to see groups shrink from. 7 ish mm ctc  to go to about half that size,
    ​so u can tune your barrel to match a pellet for max accuracy or scope barrel alinment or at 6 or 12 oclock for barrel droop.
    ​and its helps with wind drift  in a certin kida way. cuz when the barrel and scope are trued up. only the wind drifiting left or right will make the pellet go left and right before and aft of your sight in distance.
    ​if martin didn’t believe in it he wouldn’t make it.
    ​I have a bm 500 and I swear indexing works.

    ​before I bought it I had a discussion with martin and after getting and using my rifle  I’m thankful I bought a rifle with thimble.
    ​and the pellet is much easer to load  with a thimble rifle vrs a non thimble rifle.
    ​sooo much better. glass smooth .

    I just hope when you contact martin you have all the info you need to make the right choice.
    ​if your target shooting or hunting at xtreme ranges or need max accuracy at close  range a thimble
    is the right way to go.

    NOTE YOU CAN ONLY GET A SINGLE SHOT RIFLE TM OR BM WITH THIMBLE.
    ​YOU CAN NOT GET A MAGAZINE RIFLE WITH THIMBLE

    aa, I am a hunter. The HM1000X will suit me fine. I will get a repeater. I just want an accurate gun that will last for years. I made the right choice for me.

    Thanks everyone.

    Indexing allows a barrel that is not perfectly straight to aline with the ‘Y’ axis (vertical) by turning the barrel. Realize that no barrel is perfectly straight. If an indexed barrel is alined to the ‘Y’ axis (vertical) and zeroed to a specific distance, as the distance to the target changes then the shooter will only need to adjust for the change in distance on the vertical plane (hold over). If the barrel was not indexed to the vertical plane, then as the distance to the target changed the shooter would need to adjust both the ‘X’ and ‘Y’ axis (horizontal and vertical). If a barrel is not alined to the vertical axis, the shooter would need to re-zero the rifle if the target distance changed from the original zero. There is a real value in an indexed barrel, but you will give up a magazine option and have to load a single pellet manually.
